SN74CBTLV3384DW (TEXAS INSTRUMENTS)

The SN74CBTLV3384DW is a 10-bit FET Bus Switch allows connections to be made with minimal propagation delay. The device is organized as dual 5-bit bus switches with separate OE inputs. It can be used as two 5-bit bus switches or one 10-bit bus switch. When OE is low, the associated 5-bit bus switch is on and A port is connected to B port. When OE is high, the switch is open and the high-impedance state exists between the two ports. This device is fully specified for partial-power-down applications using Ioff. The Ioff feature ensures that damaging current will not backflow through the device when it is powered down. The device has isolation during power off. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor, the minimum value of the resistor is determined by the current-sinking capability of the driver.
